LO G-DUMPING DEVICE.

Specification of Letters Patent.

'Patented March 24, 1908.

Application filed JulyllS, 1907. f- Serial No. 384,441.

To all whom it may concern:

Be it knownv that I, WILLIAM D. LINK, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Log- Dumping Devices, of which the following is a specification.

This invention relates to log dumping devices and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.

The object of the invention is to provide means whereby vehicles, ordinarily cars, may be dumped so that they may he unloaded expeditiously.

The invention is illustrated in the accompanying drawing.

Figure 1 is a plan view of the apparatus. Fig. 2 a cross section of the same. E ig. 3 a detail oi the bolster locking mechanism for the dumping bar.

1 marks the track; 2 the stringers on which the rails are laid; 3 the trestle supporting track; 4 the car. The car is provided with the usual side beams 5. rIhe stationary holsters 6 are secured to the side beams 5. The two holsters 6 are arranged a short distance apart leaving a space between them, and the tilting holster 7 is ar ranged in this space.

The bolster is preferably mounted so it may tilt in either direction. on the rods 3, the stationary holsters 6 holding it in place.

The log ways 9 are arranged on each side of the track in position to receive the logs as they are dumped from the car.

It is desirable to be able to engage the holsters and dump the cars at any position along the log ways, and also desirable to operate upon both holsters of the car at once. In the present device this is accomplished.

Dumping bar 10 extends along the track preferably the full length of the log ways. It is connected by the thrust bars 11 with the rock arms 12. The rock arms 12, are mount ed on the shafts 13. Rock arms 14 are also fixed on the shafts 13, and the rock arms 14 are connected with the pitmen 15. These pitmen are connected with the cross heads 16, and the cross heads are connected with the pistons 17, 'forming part of the engines 1S, the engines being provided with the usual valves and other mechanism for controlling them.

It will he noted that the hars 1.0 are raised at each side and that either may he operated p so that the logs may be dumped either to one side or the other as desired. The shafts 13 extend preferably the full length of the bars 10, and numerous thrust bars 11., are provided so that the bar 10 may have ample support.

Bars 10 will be in position to engage the holsters in any position the car may be placed along the log ways.

Vhen sui'licient power is provided. to operate the apparatus rapidly, the holsters are apt to over-run the bars 1() so that an undesirable shock is produced as the holsters return under the influence of gravity. To prevent this, I prefer to lock the holsters with the bars 10 as the bars are elevated. The holsters are provided with the under-cut grooves 20, one at each end. The bars 10 are provided with the spline 21 extending the i'ull length of the hars. An oscillating arm 22, extends Jfrom the har 1() and this is connected with the rock arm 12 by the connection 23. It can readilybe observed as the rock arm 12 is elevated the bar 10 will be rocked through the iniiuenoe of the connection 23 and the oscillating arm 22 so that after the har enters the groove 20, the spline 21 is turned into the under cut portion and the bar 10 and holsters 7 are securely locked together.

I prefer to make the connection 23 a yielding and adjustable one; and in order to make it yielding I provide pipe 24 which is connected with the arms 12 by the rod 25. The pipe 24 has the iiange nut 26 and the rod 27 extends through this flange nut into the pipe. The spring 28 is arranged around the rod within the pipe.

Nut 29 is secured to the end of the rod and the spring 28 extends between the nut 29 and the iange nut 26 adjusting nut 30 is screwed onto the rod outside of the pipe so that the length of the connection 23 may be adjusted by this nut. By adjusting the length ot the connection 23, the position of the spline 21 may be controlled so that it may be made to enter the under cut groove 20. By making the connection yielding it permits a further movement of the parts after it has engaged the under cut portion of the groove. This obviates the necessity for a nice adjustment and permits oflocking the parts together at an earlier point in the travel of the bar 10.

In order to hold the bars 10 in position to enter the grooves 2() I provide the guides 19 which are secured to the log ways and extend upwardly so as to engage the hars 10. After the hars 10 enter the grooves they are held in position and guided hy the holsters 7. In additlon to saving the holsters and parts from shock, looking the hars 10 with the holsters prevents the disengagement of the hars 10 from the holsters so that the hars 10 are guided when out of engagement with the guiding hars 19 so that the return of the hars 10 to the proper place on the guides 19 is assured.

What I claim as new is:

1. In a log dumping device the combination with a track; of a dumping har extending along the track and adapted to dump a car independently of a movement of the track; and means for actuating the har.

2. In a log dumping device the comhination with a track; of a dumping har extending along the track; and adapted to dump a car independently of a movement of the track; and means for actuating the har com- -Erising a plurality of devices acting on the ar at different points.

3. In a log dumping device the combination with a track; of two dumping hars, one on each side of the track and extending along the same; and means for actuating said hars independently.

4. In a log dumping device the coinhination with a track; a car provided with tilting holsters; a har ior actuating said holsters to drop a har independently of a movement of the track and means for actuating the har.

5. In a log dumping device the comhination with a track; of two dumping hars, one on each side oi the track and extending along the same and means for locking the har and holster together while the holsters are tilted.

6. In a log dumping device the combination with a track; a car u on the track; of a dumping har extending a ong the track said har heing arranged to rock; means for elevating the har and rocking the same as the har is elevated; a car holster on said car heing engaged hy said har with the car upon the track; and means on the holster for locking it with the har as the har rocks.

7. In a log dumping device the combination with a track; a car; tilting holsters on the car having under cut grooves therein; a dumping har extending along the track in position to enter the grooves to tilt the holsters; a spline along the har adapted to engage the under cut groove and lock the har with the holsters as the har rocks; and means `for actuating and rocking the har.

8. In a log dumping device the combination with a track; a rock shaft; means for operating the yrock shaft; a dumping har; rock arms on the shaft; connections hetween the shaft and the har for communicating the movement of the rock shaft to the har; an oscillating arm on the har; a connection hetween rock arm and said oscillating arm to rock the har as it is actuating; a car; a car holster on said car; said. holster having an undercut groove into which the har and spline enter, the spline acting on the groove to lock the har to the holster.

9. In a log dumping device the combination with a track; a car; til-ting holsters on the car; a har extending along the track for tilting the holster; locking devices for locking the har and holsters together; comprising an oscillating arm on said har; a rock shaft and a yielding connection between the oscillating arm and the rock arm for rocking the har as it is elevated, said yielding connection comprising the pipe 24 with the 'flange nut 26, the rod 27 extending into the pipe; nut 29 on the end of the rod; the spring 28 between nut 29 and 'flange nut 26; and the adjusting nut 30.

10. In a log dumping device the comhination with a track; the log way along said track; and devices adapted to engage and dump cars independently of a movement of' the track at various points along the log way.

11. In a log dumping device the combination with a track; the log way along said track; and devices at each side of the track adapted to engage and dump cars independently of a movement of the track to either side at various points along the log way.

12. In a log dumping device the comhination with a track; a log way along the track; a car; two tilting holsters on the car; and means for engaging and simultaneously tilting hoth holsters at various points along the log way.

13.
